Detailed Description

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

referring to fig. 1-3, a grasping forceps of an abdominal cavity surgical forceps comprises two forceps handles 110, wherein one end of each forceps handle 110 is provided with a hook 200, the other end of each forceps handle 110 is provided with a mounting part 120, and the hooks 200 are perpendicular to the end faces of the forceps handles 110;

the mounting portion 120 is provided with a mounting hole 121, and the mounting portions 120 of the two clamp handles 110 are hinged through a rotating shaft 300;

the clamp handle 110 is provided with saw teeth 111, and when in use, a target object can be clamped by the engagement of the saw teeth, so that the functions of dragging, pulling and the like are realized;

when in use, the object can be hooked by the hook, so that the hooking function is realized.

The hook 200 is provided with an arc surface 210, and the hook 200 and the arc surface 210 can be used for realizing the touch and pushing functions. Specifically, when an obstacle is encountered, the hook 200 can be opened to separate the obstacle from the two sides by opening the hook 200, and the opening and closing actions of the crocodile mouth with a small range (the crocodile mouth is formed by the saw teeth 111 after the two forceps handles are connected) are matched to realize the touching of different angles and ranges of human tissues, and the cambered surface 210 can avoid damaging the target object. In this process, the two hooks form a moment arm structure within an angle range (the joint of the hooks and the clamp handles and the joint of the clamp handles and the hinge joint of the clamp handles and the rotating shaft 300, and the mounting hole 121 are formed together). The mounting hole 121 is for fitting with the abdominal forceps.

Further, referring to fig. 4-5, because the size requirements for the hooks are different under different use conditions, if multiple grippers with different sizes are prepared for replacement at the same time, the original purpose of the scheme is not overcome, so that the applicant designs the hooks into a detachable structure, and can directly replace the hooks with different sizes according to the needs. The method comprises the following steps:

the hook 200 is provided with a plug groove 201, an elastic mounting seat 510 is fixed at the closed end of the plug groove 201, an elastic cover 520 is fixed on the elastic mounting seat 510, an elastic object 530 is filled in the elastic cover 520, and the elastic object 530 is made of a high-elasticity material such as high-elasticity polyethylene carbon fiber, high-elasticity rubber and the like;

the first screw 410 is assembled with the elastic mount 510 through screw threads after passing through the hook 200 to fix the elastic mount 510;

the elastic cover 520 is pressed by the end surface of the plugging rod 130 and generates elastic deformation, and the elastic cover 520 and the elastic object 530 generate elastic deformation and generate right pushing force on the plugging rod 130;

the plugging rod 130 is arranged on the clamp handle 110, the plugging rod 130 is provided with a notch 131, the notch 131 and the fixed seat 610 are assembled and fixed through the second screw 420, the fixed seat 610 is fixedly connected with one end of the elastic piece 620, the other end of the elastic piece 620 is fixedly connected with the retaining seat 630, and the elastic piece 620 is made of elastic materials such as an elastic metal piece, an elastic plastic piece and the like;

the open end of the inserting groove 201 is provided with a stopping protrusion 220, and a stopping table 221 is arranged inside the stopping protrusion 220; the cross-sectional area between the retaining projections is smaller than the cross-sectional area of the insertion groove 201 (cross-section in the left view direction in fig. 5);

when the elastic piece 620 is not installed in the inserting groove 201, it is distributed at a certain angle with the closed end of the notch 131, and at this time, the distance between the two retaining seats 630 is greater than the maximum distance between the retaining protrusions. When the plugging rod is placed into the plugging groove, the retaining seats 630 are pressed by the retaining protrusions to overcome the elastic force of the elastic pieces and approach each other so as to reduce the distance between the retaining seats 630, until the retaining seats 630 pass through the retaining protrusions, the retaining seats 630 are far away from each other under the action of the elastic force of the elastic pieces and are tightly attached to the inner side surfaces of the plugging groove, the plugging rod is moved by the elastic force of the elastic cover and the elastic matters until the retaining seats are tightly attached to the retaining platforms 221, so that the retaining rods can be fixed, and the plugging rod is prevented from being separated from the plugging groove.

Preferably, the outer wall of the socket rod 130 is clamped with the inner wall of the stopping protrusion 220 after the assembly is completed, thereby preventing the hook 200 from loosening.

Referring to fig. 5-6, preferably, in order to facilitate the removal of the hook 200, an ejection hole 202 penetrating through the sidewall of the insertion groove may be provided on the sidewall of the insertion groove at a position corresponding to the retaining seat, the ejection hole 202 may be assembled with the ejection rod 720, and the ejection rod 720 passes through the ejection hole 202 to press the retaining seats close to each other until the retaining seats can pass through between the retaining projections, and at this time, the insertion rod is directly pulled out.

The two ejector rods 720 are respectively fixed on the inner sides of the supporting plates 710, one ends of the two supporting plates 710 are respectively connected and fixed with the two ends of the connecting plate 700, the connecting plate and the supporting plates 710 are supported by elastic materials, elastic metal sheets, elastic plastic sheets and the like, when the push-out device is used, the two supporting plates 710 can be separated from each other, then are sleeved outside the hooks so that the two ejector rods are respectively arranged in the ejector holes 202, then the ejector rods can be pressed to mutually compress and approach the retaining seats by pressing the supporting plates 710, and finally the inserting rod can be taken out.

The connecting plate, the supporting plate and the ejector rod 720 together form a switch clamp, and the switch clamp can not be arranged on the hook 200 when the grasping forceps are used. This prevents the switch clamp from affecting use.

Preferably, in order to facilitate the installation of the retaining seat into the insertion groove, a guiding inclined plane 632 may be provided on the retaining seat, and in use, the retaining protrusion may be conveniently pressed by the guiding inclined plane 632 to bring the retaining seats close to each other.

Referring to fig. 7-12, the grasper of the present invention is controlled by the control lever B, but in normal use, it is often necessary to adjust the distance between the grasper and the adjustment barrel B100, thereby adjusting the shear force applied by the control lever B to the grasper, i.e., controlling the shear force of the grasper.

In addition, in the actual use process, the control rod also needs to be subjected to length adjustment, so that the control rod is suitable for different use conditions. However, there are still techniques for adjusting the control lever, and therefore, the applicant has made the following improvements:

one end of the control rod B is assembled and fixed with the control end, and the other end of the control rod B is assembled with a control device (a device for applying force to the control rod). The control rod B comprises a rod body B200 and a locking component, one end of the rod body B200 is arranged in a first channel B101 of the adjusting cylinder B100, the other end of the rod body B200 is fixedly assembled with the control end, one end of the rod body B200 arranged in the first channel B101 is a sliding part B210, the sliding part B210 is fixedly assembled with one end of a sliding rod B220, the other end of the sliding rod B220 respectively passes through a limiting through groove B121 and a locking through groove B327 and is fixedly assembled with one end of a connecting strip B520 through a first screw B611, the other end of the connecting strip B520 passes through a second connecting groove B512 and is arranged in the first connecting groove B511, and the second screw B612 passes through a control end B510 and the connecting strip B520 to fix the connecting strip B520 in the first connecting groove B511;

the limiting through groove B121 is arranged on the limiting block B120, and the limiting block B120 is fixed in the first channel B101.

One end surface of the adjusting cylinder B100 far away from the grasping forceps is welded and fixed with one end surface of the fixed cylinder B330, and the other end surface of the fixed cylinder B330 is welded and fixed with one end of the movable clamping cylinder B320;

the fixed cylinder B330 and the movable clamping cylinder B320 belong to locking components, and the sliding rod B220 passes through the fixed cylinder B330 and can be assembled with the fixed cylinder B in a sliding way;

the slide bar B220 also passes through a locking through groove B327 on the movable clamping cylinder B320, the movable clamping cylinder B320 comprises a first clamping cylinder B321 and a second clamping cylinder B322, when in an initial state (state of fig. 10), the first clamping cylinder B321 is tightly attached to the second clamping cylinder B322, and an attaching gap B323 between the first clamping cylinder B321 and the second clamping cylinder B322 is a plane;

in the adjustment state (fig. 11 state), the first card cylinder B321 is separated from the second card cylinder B322, and the attaching gap B323 is the interval between the end faces of the first card cylinder B321 and the second card cylinder B322;

the locking through groove B327 is formed by a first clamping cylinder B321 and a second clamping cylinder B322; when the first clamping cylinder B321 and the second clamping cylinder B322 are not limited by the locking cylinder B310, the first clamping cylinder B321 and the second clamping cylinder B322 automatically form the state of fig. 11 through self elasticity, that is, the first clamping cylinder B321 and the second clamping cylinder B322 have elasticity, and when the locking cylinder B310 is limited, the locking cylinders overcome the elasticity of the first clamping cylinder B321 and the second clamping cylinder B322 to enable the first clamping cylinder B and the second clamping cylinder B322 to be mutually closed.

The fixed cylinder B330 is fixedly connected with one end of the connecting cylinder B130, and the fixed cylinder B330 can be fixedly connected with the connecting cylinder B130 (bypassing the locking component) from the outside of the adjusting cylinder B100 through the connecting sheet B110; the inside of the connecting cylinder B130 is a hollow connecting inner cylinder B131, the other end of the connecting cylinder B130 is arranged in the second connecting groove B512, the connecting strip B520 is arranged in the connecting inner cylinder B131, and the end part of the sliding rod B220 is arranged in the connecting inner cylinder B131 and is assembled and fixed with the connecting strip B520;

a switch hole B312 and a screwing hole B311 are arranged in the locking cylinder, and the screwing hole B311 is assembled with the outer wall of the fixed cylinder B330 in a screwing way through threads;

the section profile of the opening and closing hole B312 at the A-A is composed of a first cambered surface B3121, a second cambered surface B3122 and a connecting cambered surface B3123, which is similar to an elliptic profile, and a first long axis end B3125 and a first short axis end B3124 are arranged in the profile;

when the movable cartridge B320 is compressed (fig. 10), the outer contour of the section A-A is also elliptical or elliptical-like, and includes a second major axis end B326 and a second minor axis end B325.

In the initial state, the first short axis end B3124 and the second long axis end B326 are clamped, so that the elastic forces of the first clamping cylinder B321 and the second clamping cylinder B322 are overcome to close each other to form the state of fig. 10, and at this time, the cross-sectional area of the locking through groove B327 at the section A-A is the smallest, that is, the sliding rod B220 is clamped by the locking through groove B327, so that the sliding rod cannot move in the axial direction thereof. Preferably, the outer contours of the sliding rod B220 and the sliding portion B210 are non-circular in the view of the section A-A, i.e. the sliding rod B220 and the sliding portion B210 cannot rotate circumferentially in the second channel. This can prevent the body of rod from taking place circumferential rotation and influencing the use when using.

When the length of the control rod is required to be adjusted from the state of fig. 10 to the state of fig. 11, the locking cylinder B310 is rotated ninety degrees first, so that the second short axis end B325 corresponds to the first long axis end B3125, and since the distance between the first long axis end B3125 and the attaching gap B323 is greater than the distance between the first short axis end and the attaching gap B323, the restriction on the first clamping cylinder B321 and the second clamping cylinder B322 is reduced or even eliminated, the first clamping cylinder B321 and the second clamping cylinder B322 are separated under the action of the elastic force of the first clamping cylinder B321 and the second clamping cylinder B322 to form the state of fig. 11, at this time, the cross section area of the section of the locking through groove B327 at A-A is the largest, that is, the sliding rod B220 is not clamped any more, then the sliding rod B220 is pulled by the control end B510 to move in the axial direction, that the length of the control rod B can be controlled, and after the adjustment, ninety degrees of the locking assembly is reversely rotated, so that the state of fig. 11 is restored to the state of fig. 10.

Further, in order to firmly clamp the slide bar B220, a plurality of grooves B221 may be formed in the slide bar B220, and then a plurality of protrusions B324 capable of being engaged with the grooves are formed on the inner side surface of the locking through groove B327, so that the slide bar can be well fixed through the engagement of the protrusions B324 and the grooves B221 during use.

Preferably, the protrusions B324 are made of elastic soft materials, such as rubber and silica gel, and when the sliding rod is used, the protrusions B324 deform to increase the pressure between the sliding rod and the first clamping cylinder B321 and the second clamping cylinder B322, so that the friction force is increased, and the fixing performance of the sliding rod is improved;

further, in order to limit the rotation angle and rotation position of the locking cylinder and prevent the first short axis end B3124 from being not clamped with the second long axis end B326, the fixing of the sliding rod is not stable enough, and the first limiting ring B141 and the second limiting ring B142 may be disposed outside the adjusting cylinder B100 and the connecting cylinder B130, respectively. Referring to fig. 12, in the state of fig. 10, the left end face of the locking cylinder B310 is tightly attached to the first limiting ring B141, and in the state of fig. 11, the right end face of the locking cylinder B310 is tightly attached to the second limiting ring B142, so that the axial displacement of the locking cylinder after rotating 90 ° is inferred by the screw thread parameters of screwing the locking cylinder and the fixing cylinder, and the displacement is limited by the first limiting ring B141 and the second limiting ring B142.

Referring to fig. 12, in the state of fig. 11, a yielding interval B102 is formed between the right end surface of the movable card cylinder B320 and the left end surface of the connecting cylinder B130, and the yielding interval B102 is used for providing a space for the state change of the first card cylinder B321 and the second card cylinder B322, so as to prevent the first card cylinder B321 and the second card cylinder B322 from being interfered when the state change occurs.

The present invention is not described in detail in the present application, and is well known to those skilled in the art.

The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden.
